Please review its claims and source references carefully before acting on them. # Summary Remotely vended S3 credential maps are merged wholesale into live client properties, allowing endpoint, proxy, factory, and credential-provider overrides. # Affected Maven coordinates * primary shipped client artifact: `org.apache.iceberg:iceberg-aws` * bundle artifact: `org.apache.iceberg:iceberg-aws-bundle` # Attacker prerequisites * control over the affected catalog response, configuration surface, or spec-consumed routing value * a client or service that honors the affected configuration without an additional allow-list # Impact * Compromised or malicious credential-vending service can redirect AWS traffic to attacker-controlled endpoints * Same service can force use of arbitrary classpath extensions already present in the engine process * This expands the blast radius from "credential issue" to "transport manipulation / class-instantiation issue" # Proof status I reproduced this locally with a targeted reproducer or exploit. The observed result matches the trigger and impact described above. # Key source references * org.apache.iceberg.aws.s3.S3FileIO * org.apache.iceberg.aws.S3FileIOAwsClientFactories * org.apache.iceberg.aws.AwsClientFactories * org.apache.iceberg.aws.AwsClientProperties * org.apache.iceberg.rest.RESTSessionCatalog Current severity assessment [2]: Important [1] https://iceberg.apache.org/security/ [2] https://security.apache.org/blog/severityrating/ -- This is an automated message from the Apache Git Service.
